Abstract: A collimator lens unit in which an aperture limit stop formation member and a collimator lens are integrally disposed in a cylindrical member is inserted in a lens-barrel hole of the module casing so as to be reciprocatable in an optical axis direction, and a light-emitting unit is fixed in the lens-barrel hole, with an optical axis of a light source aligned with an optical axis of the collimator lens. A long hole through which an adjust pin is penetrated so as to be reciprocatable in the optical axis direction is formed in a peripheral sidewall of the lens-barrel hole, and a fitting portion in which the adjust pin is fit is formed in an outer peripheral surface of the cylindrical member. On an inner peripheral surface of the lens-barrel hole, at a position opposed to the fitting portion, bearing portions in contact with the outer peripheral surface of the cylindrical member are formed.

Abstract: In an optical code detection system and method, infrared pulses are utilized to detect the presence of an object within the range of an optical imaging device, but the image of an infrared pulse reflected from the object is also analyzed to determine the distance between the object and the imaging device. An illumination pulse is then produced to illuminate the optical code on the object, and the characteristic of that pulse, such as duration, are controlled to provide appropriate exposure for an object at the detected distance.

Abstract: A liquid lens is mounted in a lens opening provided in a photographic instrument by making use of a mounting member made of a material which transmits light of predetermined wavelength and includes an inner wall shaped and dimensioned to receive the periphery of the lens in spaced, opposed relationship. The mounting member includes a portion mounted or to be mounted to the optical instrument.

The light may be injected from an edge of the guide member remote from the opening, through the guide member, and into the mounting member.

Abstract: A relatively rapidly moving object is imaged with a sensor incorporating a rolling electronic shutter, while using flash illumination which is comparable to or dimmer than ambient light. This is achieved by utilizing a physical shutter between the object and sensor which is synchronized to the flash. Preferably, the physical shutter is also operated so as to be open for a time interval which is coextensive with the presence of the flash. Preferably, an optical mechanism is provided between the object and sensor which causes the image to be focused when the light is flashed and blurred otherwise. Preferably, an optical filter is positioned between the object and sensor, and this filter is constructed to transmit to the CMOS sensor light at the wavelength of the flashing light source but to attenuate ambient light.
